As if such an event were not already impossible to forget, it doesn’t help that visitors who now visit the zoo are greeted by two 26-foot-long tiger sculptures at the front gate.

“Two 26-foot tigers will be greeting visitors to the San Francisco Zoo through February 28th, 2011!” reads a press release from Trinity Eight PR, which is handling publicity for the sculptures. “Fortunately for art lovers, Digital Origami Tigers are monumental public sculptures that combine artistic, visual, ecological, and educational value regarding the endangerment of tigers around the world.”

You can even watch the video of zoo employees rolling out the sculptures below.
